Product state display system, and program and recording medium for the same

ABSTRACT

A product state display system operates so that a person who looks at a pseudo living matter can easily understand the state of an industrial product at first glance in the case where the state of the product is represented by displaying the pseudo living matter. The pseudo living matter displayed on a display device shows both the “aging state” corresponding to the “progress state of time-dependent deterioration” of the industrial product within an endurance period and the facial expression corresponding to a “temporary state” of the industrial product. Accordingly, it is possible for a person who looks at the pseudo living matter to quickly and easily understand two states (progress state and temporary state) of the industrial product with just one glance.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a product state display system for displaying a state of an industrial product, which has a changeable operating state, on a display device by use of a pseudo living matter, and relates to a program and a recording medium for the same.

2. Description of the Related Art

Previously, a device has been proposed in which a representation entity (hereinafter referred to as a “pseudo living matter”) designed to resemble a person, an animal, an animation character, or the like is represented as a two-dimensional or three-dimensional image in a vehicle to notify a driver of information about the state and the like of the vehicle through the pseudo living matter (Japanese Unexamined Patent Publication No. 2001-219796).

The above-described state of the vehicle is a temporary state of the vehicle which has been detected by a fuel level sensor or the like, and is represented by using a pseudo living matter realized with an image of an animation character and by providing various facial expressions to the pseudo living matter.

According to the aforementioned Japanese Unexamined Patent Publication, a temporary state of a vehicle is represented by the facial expression of the pseudo living matter, so that a driver can recognize the state of the vehicle with the use of a more familiar image expressed by the pseudo living matter.

However, in the conventional display method, information that should be displayed by use of a scale or the like is simply replaced with the facial expression of the pseudo living matter to be represented. Accordingly, as in the case of the remaining amount of fuel or the like, when everyone can understand the state of the vehicle, there is no problem. However, when understanding the structure and the like of a product is required as in the case of the state of an engine, there arises the following problem: factors that reduce the endurance period (life) of the vehicle and that cause many failures are produced. That is, since not every driver can understand the structure of the engine and the meaning of a particular measured value, it is difficult for the drivers and the like to correctly understand whether the state of the vehicle is normal or abnormal, what kind of condition is or could become a problem, or the like, even if information which should be displayed by use of a scale or the like, is simply replaced with the facial expression of the pseudo living matter and the state of the vehicle can be thereby recognized with an image that is familiar. Accordingly, even when the conventional display method is used, the following problem cannot be solved: a driver unconsciously reduces the endurance period of the vehicle, or a factor that results in a failure is produced.

Moreover, although the conventional display method is suitable for the case where a condition that is temporary and can be restored by replenishment is represented, as in the case of fuel, the conventional display method is not suitable for representing a thing or condition which has an endurance period (life) and which is gradually deteriorated with time without the ability to be restored, once the thing has been deteriorated, as in the case of an engine, a lamp, or the like. This is because the facial expression of the pseudo living matter is displayed only at the beginning but is not displayed again.

Furthermore, the conventional display method provides a method for representing a piece of information indicating the state of the vehicle by use of different facial expressions of the pseudo living matter. Accordingly, a plurality of pieces of information cannot be simultaneously represented.

On the other hand, in Japanese Unexamined Patent Publication No. Hei 11(1999)-250395, an invention has been disclosed in which a plurality of states are simultaneously represented by two pseudo living matters (agents). According to this Japanese Unexamined Patent Publication, a plurality of pieces of information can be simultaneously provided to a driver by simultaneously displaying a main pseudo living matter and a helping pseudo living matter having a different appearance from that of the main pseudo living matter. However, when a plurality of pseudo living matters are simultaneously displayed, a person who looks at them cannot understand, at first glance, what states of a product are being represented. In particular, it is difficult for a driver of a vehicle to carefully look at a plurality of pseudo living matters while driving.

SUMMARY OF THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described using the drawings.

FIG. 1 is a left side view of a two-wheeled motor vehicle according to a preferred embodiment of the present invention. FIG. 2 is a rear view showing a meter panel and the surroundings thereof of a vehicle body cover. FIG. 3 is a view showing the meter panel.

In FIG. 1, reference numeral 1 denotes a scooter-type two-wheeled motor vehicle, which is an example of a product according to preferred embodiments of the present invention. This two-wheeled motor vehicle 1 preferably has the following schematic structure: a front fork 4, at the lower end of which a front wheel 3 is pivotally supported by the front end of a vehicle body frame 2 so as to allow steering to the left and the right; a unit-swing engine 5 is supported by the rear of the vehicle body frame 2 so as to be able to vertically swing; a rear wheel 6, which is placed inside of the rear end of the engine 5, is pivotally supported at the rear end thereof; a container device 7 is placed above the engine 5; a seat device 8 is mounted on the container device 7; a fuel tank 9 and a radiator 29 are mounted in this order in front of the engine 5; and the vehicle body frame 2 is surrounded by the vehicle body cover 10 made of resin.

Further, the vehicle body frame 2 preferably has the following schematic structure: the front ends of left and right side frames 2 d are connected to a kingpin tube 2 a, which pivotally supports a kingpin 4 a of the front fork 4; left and right grip support members 2 f are fixed to the top ends of left and right main brackets 2 e extending from the rear ends of the left and right side frames 2 d backward and obliquely upward; and the left and right grip support members 2 f are coupled to each other by a rear frame 2 g, which is almost U-shaped in view from the rear. Incidentally, in each of the left and right side frames 2 d, upper and lower side pipes 2 b and 2 c are arranged so as to have a two-stage almost L-shaped form as viewed from the side, and the rear ends of these are connected to each other through the main bracket 2 e.

Moreover, the kingpin 4 a, which is vertically placed in the middle of the front fork 4 in the vehicle width direction to extend upward, is pivotally supported through a bearing by the kingpin tube 2 a, which is at the front end of the vehicle body frame 2, so as to allow steering to the left and the right. The middle portion 16 a of a steering handle 16 is detachably fixed to the top end of the kingpin 4 a through a handle bracket 4 b by a bolt. The steering handle 16 has the middle portion 16 a, which is preferably made of a round steel pipe and almost horizontally extends, and a left portion 16 b and a right portion (not shown), which rise from the left and right ends of the middle portion 16 a outward and obliquely upward and almost horizontally extend. A handle cover 17 made of resin is attached so as to surround the middle portion 16 a and the left and right inclined portions of the steering handle 16. The handle cover 17 rotates with the steering handle 16.

Further, the vehicle body cover 10 has a cowling 11 for covering the vicinity of the rear of the front wheel 3 from the front of the kingpin 4 a, an undercover 12 for covering the left and right lower portions of the vehicle body subsequently to the foregoing, a leg shield 13 for covering the rear of the kingpin 4 a, a footboard 14 constituting a footrest section, and side covers 15 for covering the left and right portions of the seat device 8.

Further, as shown in FIG. 2, an inner panel 18 made of resin is attached to the opening surrounded by the upper edge of the cowling 11 and the upper edge of the leg shield 13 so as to block the opening. A handle opening 18 a, into which the handle bracket 4 b at the top end of the kingpin 4 a is inserted, is formed in the middle of the inner panel 18 in the vehicle width direction. Grid portions 18 b are formed on the left and right of the handle opening 18 a. These grid portions 18 b are made by forming a plurality of slits 18 c in the inner panel 18 so as to extend in the horizontal direction. Speakers of a stereo unit are placed inside the grid portions 18 b.

Moreover, a meter opening 18 d is formed in front of the handle opening 18 a and the grid portions 18 b of the inner panel 18. As shown in FIG. 3, a meter panel 30, in which meters including a speedometer 31, a tachometer 32, a switchable tripmeter 33, a water temperature gauge 34, a fuel gauge 35, left and right direction indicator display units 36 a and 36 b and the like are unitized, is fixedly placed in the meter opening 18 d. Furthermore, a multi-display unit 41, a select (SELECT) button 42, and a reset (RESET) button 43 are fixedly placed in the switchable tripmeter 33.

The multi-display unit 41 is preferably a transmissive liquid crystal display device. On the multi-display unit 41, a pseudo living matter can be displayed by a product state system (hereinafter referred to as “system”) 50 to be described later. Further, display switching between a pseudo living matter display screen and an odometer/tripmeter display screen can be performed by pushing the select button 42. Furthermore, the tripmeter can be reset by pushing the reset button 43.

Moreover, a meter visor 20, which prevents light from the front from directly striking dials of the meter panel 19 and which functions as a guide member for guiding wind or air, is placed in front of the meter panel 19 of the inner panel 18.

Further, a large screen (windshield plate) 24 is attached to the top end of the front surface of the cowling 11 to be slightly less inclined than the meter visor 20 (to make a slightly smaller angle with the vertical line than the meter visor 20) when the cross section in the middle in the vehicle width direction is viewed from the side of the vehicle.

Next, using FIG. 4, the functional structure of the system 50 for displaying a pseudo living matter on the multi-display unit 41 will be described. Incidentally, in the present preferred embodiment, a functional structure for displaying the state of the engine 5, as an example of an industrial product, on the multi-display unit 41 by use of a pseudo living matter, will be described. However, the present invention is in no way limited to this example. Further, the system 50 is preferably built by using a computer, and can execute each step (S1 to S6) to be described later by means of a program (p).

As shown in FIG. 4, functions of the system 50 are constituted by a state detection section 51 configured to detect a temporary loaded state of the engine 5, a state determination section 52 configured to determine the progress state of time-dependent deterioration of the engine 5, a pseudo living matter data management/readout section 53 configured to manage and read pseudo living matter data, and a display section 54 configured to display a pseudo living matter based on the read pseudo living matter data on the multi-display unit 41.

The state detection section 51 detects a temporary loaded state of the engine based on various kinds of information (throttle opening, engine rotation (rotation angular acceleration, rotation number, rotation variation), cooling water temperature, O₂ sensor signal, knocking occurrence level, and the like) transmitted from sensors and the like for detecting the operating state of the engine 5.

Further, the state determination section 52 determines the progress state of time-dependent deterioration of the engine 5. This state determination section 52 has a progress point estimation section 55 configured to estimate, based on the temporary loaded state of the engine 5 which has been detected by the state detection section 51, the progress point (degree) of time-dependent deterioration of the engine 5 which has progressed due to this temporary loaded state; a progress point accumulation section 56 configured to accumulate the progress point estimated by the progress point estimation section 55; and a progress state estimation section 57 configured to estimate the progress state of time-dependent deterioration of the engine 5 based on the total progress point accumulated in the progress point accumulation section 56. Note that the progress point accumulation section 56 is a partial storage area of a memory, such as a hard disk drive (HDD), which is built in the system 50.

Furthermore, as shown in FIGS. 5( a)-(d), the progress point estimation section 55 refers to the relationship between the progress point of time-dependent deterioration of the engine 5 and the temporary loaded state of the engine 5, which relationship has been previously set by the manufacturer, and estimating the progress point of time-dependent deterioration based on the temporary loaded state of the engine 5. In FIGS. 5( a)-5(d), as examples of the temporary loaded state, engine temperature shown in FIG. 5( a), throttle opening shown in FIG. 5B(b), rotation variation shown in FIG. 5( c), and oil viscosity shown in FIG. 5( d) are shown. For example, in the case of engine temperature, as shown in FIG. 5( a), the setting is as follows: the progress point of time-dependent deterioration is high when the engine temperature is low, the progress point decreases as the temperature increases, and the progress point sharply increases when the engine temperature becomes high. This indicates the following: the progress point of time-dependent deterioration is high in the case of starting the engine before it gets warm, the progress point is low in the state where the engine is warm, and the progress point sharply increases when the engine is brought to full power to get warm.

Moreover, the pseudo living matter data management/readout section 53 has the functions of previously storing pseudo living matter data in a pseudo living matter data management section 58, which is a partial storage area of a memory, such as an HDD, built in the system 50, managing the pseudo living matter data, and reading, from the pseudo living matter data management section 58, the pseudo living matter data corresponding to the progress state of time-dependent deterioration of the engine 5 which has been determined by the state determination section 55. As shown in FIG. 6, pseudo living matters according to the pseudo living matter data stored on the pseudo living matter data management section 58 are pseudo living matters 61 a, 61 b, 62 a, and 62 b, which have faces each preferably simultaneously representing an aging state (e.g., boy or middle-aged man) and a qualitative expression (e.g., smiley or angry).

The pseudo living matters 61 a and 61 b represent the face of a boy, and are read out and displayed in the case where the state determination section 52 has determined that the time-dependent deterioration of the engine 5 has progressed to a relatively low degree. The pseudo living matters 62 a and 62 b represent the face of a middle-aged man, and are read out and displayed in the case where the state determination section 52 has determined that the time-dependent deterioration of the engine 5 has progressed to a relatively high degree.

On the other hand, the pseudo living matters 61 a and 62 a represent smiley facial expressions, and are read out and displayed in the case where the state detection section 51 has detected that the engine 5 is relatively lightly loaded. The pseudo living matters 61 b and 62 b represent angry facial expressions, and are read out and displayed in the case where the state detection section 51 has detected that the engine 5 is relatively heavily loaded.

Accordingly, if the engine 5 is relatively new and a temporary loaded state is low when the detection result by the state detection section 51 and the determination result by the state determination section 52 are combined, the pseudo living matter 61 a is read out and displayed; if the engine 5 is relatively new but a temporary loaded state is high, the pseudo living matter 61 b is read out and displayed. Moreover, if the engine 5 is relatively old but a temporary loaded state is low, the pseudo living matter 62 a is read out and displayed; if the engine 5 is relatively old and a temporary loaded state is high, the pseudo living matter 62 b is read out and displayed.

Next, using the flowchart shown in FIG. 7, a method of displaying a pseudo living matter on the multi-display unit 41 of the meter panel 30 by utilizing the system 50 according to the present preferred embodiment will be described.

First, after the engine 5 of the two-wheeled motor vehicle is started, the temporary loaded state of the engine 5 is detected by the state detection section 51 (step S1). This temporary loaded state is detected based on throttle opening, engine rotation, cooling water temperature, O₂ sensor signal, knocking occurrence level, and the like, as described previously. This detection result is utilized by the state determination section 52. Moreover, engine rotation information is reflected in the operation of the tachometer 32, and cooling water temperature information is reflected in the operation of the water temperature gauge 34.

Next, in the progress point estimation section 55, based on the temporary loaded state of the engine 5 that has been detected by the state detection section 51, the progress point (degree) of time-dependent deterioration of the industrial product that has progressed due to this temporary loaded state is estimated (step S2). This estimation of the progress point is performed based on the temporary loaded state of the engine 5 by referring to the relationship between the degree of progress of time-dependent deterioration of the engine 5 and the temporary loaded state of the engine 5, which relationship has been previously set by the manufacturer as shown in FIGS. 5( a)-(d). Then, the estimated progress point is stored on the progress point accumulation section 56 and accumulated therein (step S3).

Subsequently, in the progress state estimation section 57, based on the total progress point accumulated in the progress point accumulation section 56, the progress state of time-dependent deterioration of the engine 5 is estimated (step S4).

After that, the pseudo living matter data management/readout section 53 reads, out of the plurality of bits of pseudo living matter data managed in the pseudo living matter data management section 58, the data of the pseudo living matter which is in the aging state corresponding to the progress state determined by the state determination section 52 and which shows the facial expression corresponding to the temporary state detected by the state detection section 51 (step S5). Then, based on the pseudo living matter data read in step 5, the display section 54 displays, on the multi-display unit 41, the pseudo living matter which is in the aging state corresponding to the progress state determined by the state determination section 52 and which shows the facial expression corresponding to the temporary loaded state detected by the state detection section 51 (step S6). Note that part of the above-described steps or a detailed process in each step may be omitted as long as the effects and advantages of the present preferred embodiment to be described below are achieved.

As described above, according to the present preferred embodiment, the facial expression of the pseudo living matter displayed on the multi-display unit 41 corresponds to the temporary “loaded” state of the engine 5. Accordingly, it is possible even for a person who does not understand the structure and the like of the product to understand the technical meaning of the state of the product by viewing a familiar, easily understandable facial expression of the pseudo living matter.

Further, according to the present preferred embodiment, the pseudo living matter displayed on the multi-display unit 41 shows the “aging state” corresponding to the “progress state of time-dependent deterioration” of the engine 5 within an endurance period, and is therefore suitable for representing a thing that is gradually deteriorated with time and that cannot be restored once the thing is deteriorated.

Moreover, according to the present preferred embodiment, the pseudo living matter displayed on the multi-display unit 41 shows both the “aging state” corresponding to the “progress state of time-dependent deterioration” of the engine 5 within the endurance period and the facial expression corresponding to the “temporary state” of the engine 5. Accordingly, it is possible for a person who looks at the pseudo living matter to understand the two states (progress state and temporary state) of the engine 5 at first glance. In particular, since two states are simultaneously displayed, the driver of a movable body, such as a vehicle, can understand the state of the vehicle at first glance even if the driver does not carefully look at the pseudo living matter display unit 102′ while driving. Thus, it is possible to drive safely.

Furthermore, according to the present preferred embodiment, the progress state of time-dependent deterioration within the endurance period is not simply represented by the elapsed time but represented in accordance with the temporary loaded state of the engine 5. Accordingly, for example, in the case where the temporary loaded state is high, expression can be made such that time-dependent deterioration progresses regardless of the elapsed time. Meanwhile, in the case where the temporary loaded state is low, expression can be made such that time-dependent deterioration does not progress.

OTHER PREFERRED EMBODIMENTS

-   (1-1) In the above-described preferred embodiment, as shown in FIG.     6, expression has been made using the face of a person as an example     of a pseudo living matter. However, the expression is not limited to     this, and may be made using the upper or whole body of a person.     Further, as a method of representing age, expression may be made     using a body shape, wrinkles, spots, a face shape, skin radiance, a     hair style, hair color, a hair volume, or the like. Moreover, a     pseudo living matter may be represented as moving images, whereby a     faster speed of actions represents that the pseudo living matter is     younger. Furthermore, a pseudo living matter may be displayed as a     three-dimensional image. -   (1-2) Further, the progress state of time-dependent deterioration     has been divided into two stages, such as a boy and a middle-aged     man, in the aforementioned preferred embodiment, but the present     invention is not limited to this. The progress state of     time-dependent deterioration may be divided into three stages or     four or more stages, such as a boy, a middle-aged man, and an aged     man. In addition, the facial expression thereof may be divided into     three or more stages. -   (1-3) Moreover, as shown in FIGS. 8( a)-8(c), expression may be made     using an animal instead of a person. The pseudo living matters of     this case represent a chick 63 a (FIG. 8( a)), a chicken 63 b (FIG.     8( b)), and an old chicken 63 c (FIG. 8( c)). -   (1-4) Furthermore, as shown in FIGS. 9( a)-9(c), expression may be     made using a plant instead of an animal. The pseudo living matters     of this case represent a before-full-bloom sunflower 64 a (FIG. 9(     a)), a full-blown sunflower 64 b (FIG. 9( b)), and an overblown     sunflower 64 c (FIG. 9( c)). Thus, the “progress state of     time-dependent deterioration” and “temporary state” of the engine 5     can be simultaneously represented by a simulation displaying a     facial expression on a plant or the like, which has no facial     expressions in nature. -   (2-1) Moreover, in the aforementioned preferred embodiment, the     progress state of time-dependent deterioration and the temporary     loaded state of the engine 5 have been represented by the aging     state and the facial expression of a pseudo living matter. However,     the expression is not limited to this and may be made using sound.     For example, the voice of an aged man is used in the case where     time-dependent deterioration has progressed, and the voice of a     child is used in the case where time-dependent deterioration has not     progressed. Further, a sentence, such as “it's tough,” “it's hard,”     or the like, is used in the case where the temporary loaded state is     high, and a sentence, such as “it's easy” or the like, is used in     the case where the temporary loaded state is low. Furthermore, it is     possible to combine them. For example, in the case where the     time-dependent deterioration of the engine 5 has progressed and the     temporary loaded state of the engine 5 is low, the sentence “it's     easy” in the voice of an aged man is used. -   (2-2) In addition, the progress state of time-dependent     deterioration may be represented by the speed at which a sentence is     spoken. For example, the speed of speaking is increased in the case     where time-dependent deterioration has not progressed, and the speed     of speaking is reduced in the case where time-dependent     deterioration has progressed. Further, in the case where the     temporary loaded state is high, expression may be made using the     sound of screaming or the like. -   (3-1) Moreover, in the aforementioned preferred embodiment, the     temperature and the like of the engine have been taken as examples     of temporary loaded states. However, temporary loaded states are not     limited to these. It is also possible to estimate the progress point     in consideration of operating environment, such as air temperature,     weather, and the like, using an air temperature sensor and a     humidity sensor. Furthermore, the life of the engine is not simply     determined based on how long a certain rotation number (r.p.m., for     example) has been used. The use at the temperature according to the     design reduces the life due to wear and the like because there are     mechanical stresses due to temperature change given by the number of     times of starting the engine and the thermal expansion of each part     due to the temperature and the like for actual usage. The load on     the engine, rotation variation (rotation fluctuation), the state of     oil, and the like, influence one another. Thus, wear and metal     fatigue are accumulated. Accordingly, it is also possible to set a     map or a calculation formula for estimating each influence based on     values and the like which have been theoretically or experimentally     obtained, to calculate the current progress state of time-dependent     deterioration within the endurance period based on the calculation     formula, and to make expression using the face, action, or the like     of a person according to the age. -   (3-2) Moreover, in the aforementioned preferred embodiment, the     temporary loaded state of the engine 5, which is an industrial     product, is detected. However, what is detected is not necessarily a     loaded state as long as it is a temporary state and, for example,     may be the remaining amount of fuel, the “on” and “off” of a light,     or the like, which is temporary at a certain time point. -   (4) Furthermore, the progress point may be estimated in     consideration of problems (including failures) such as a malfunction     of the product including parts, the accumulation of carbon in an     exhaust system, improper combustion due to dirt of an ignition plug     or an injector, the occurrence of knocking due to the fact that fuel     having an appropriate octane value is not used, power down due to     rotation variation or a knock sensor. For example, a problem can be     represented by a pseudo living matter that is bandaged or using a     cane. -   (5) Further, in the aforementioned preferred embodiment, the case     where a pseudo living matter is displayed on part of a two-wheeled     motor vehicle has been described. However, in addition to computers,     home electric appliances, daily necessities, and the like, movable     bodies including airplanes, vehicles, ships, and the like may be     adopted as long as they are so-called industrial products. -   (6) Moreover, the work of recording and installing the program (p)     on the system 50 in the aforementioned embodiment can also be     performed by utilizing a recording medium, such as a CD-ROM, DVD, or     other computer data memory device on which the program (p) readable     by the system 50 is recorded. -   (7) Furthermore, in the aforementioned preferred embodiment, each     step has been described to be capable of being executed by software     of the program (p). However, each step is not limited to this, and     part of each step or part of a detailed process in each step may be     executed by hardware of an existing circuit, sensor, or the like.
